Looks CG to me. Something about the way the fan falls, and that the fan spins up to that speed right away. Some of the cups fly/fall in an unnatural way. That's probably why it's so deep fried. Still well done no matter how they did it.

EDIT: also pausing and playing very quickly for a frame-by-frame some things weren't tracked properly. Almost seems like they shot it on a tripod for stability and added the camera movements in post
